Vasco da Gama host Argentinian giants Boca Juniors in the second leg of their Copa Sudamericana semi-final in the early hours of Wednesday morning, with a 1-0 aggregate lead to cling to.
Boca are two time Copa Sudamericana champions and they knocked out Vasco's fellow Brazilians Sao Paulo in the quarter-finals with a 2-1 aggregate victory.
Azul y Oro have also lifted the Copa Libertadores on six occasions and are in with a shout of being one of South America's biggest clubs.
Vasco da Gama overcame Colombian side Santa Fe 2-0 on aggregate in their last-eight clash and they arein the hunt to win the competition for the first time.
The Brazilians won a sole Libertadores title back in 1998 and the now defunct Copa Mercosur in 2000 but haven't seen any continental success since then.
Whoever comes through this tie will take on Atletico Mineiro or Montevideo City Torque in next month's final.
